BUILDEBS APPARATUS.

To all whom 'it may concern.'

Be itknown that I, JAMES DaisLnr, a resiw dent of South Framingham, inthe county of Middlesex and State of Massachusetts, have inventedcertain new and useful lmprovements in Builders Apparatus, of which thefollowing is a s ecilication.

This invention re ates to builders apparatus.

More particularly it relates to a frame work and related parts which areused in the process of building a wall. It is here villustrated anddescribed more particularly as it may be applied to a concrete wall, butits use is not limited to that and in many respects it may be applied tomasonry walls, particularly brick walls.

The invention relates in general to the structure of a frame work orstaging, by which a mold for the concrete may be supported, the supportsfor the mold-faces and means for adjusting them in properI location andat proper angles; and other features incidental to this, as will appearfrom the following description and the accompanying drawings, in which:A.

Figure l represents an embodiment of the invention in end elevation, invertical section; Fig. 2 is a detail showing the manner of applying oneof the features of the invention to a brick wall; Fig. 3 is a plan insection of a detail of Fig. l; Fig. l is an enlargement of a detail ofFig. l seen in end elevation; Fig. 5 is a perspective view of adifferent application of the invention; Fig. 6 is a plan of a detailfrom Fig. l; Fig. 7 is a side elevation in section of the same; Fig. 8is a plan in section of another' detail of Fig. l, and Fig. 9 is a planof one end of a sill, with upright removed.

This case is related in subject matter to v my copending application forpatent, Se-

rial No. 398,765, and embodies some features originally disclosedtherein.

Referring to the drawings, l represents a sill from which standards 2rise, each provided with a vertical longitudinal slot 3. rlhe cross tiesLl pass through these slots and are fastened by pins 6 which ass throughholes 5 in the standards and cross ties. Braces 7 likewise pinned to thestandards, as at 8, support the standards upright, and these standardsare hereinafter designated uprights Frequently the ground adjacent tothe base of the stagin or framework is not level or stands at a di erentelevation Specification of Letters Patent.

from the bottom. rlhe pivotal connection enables the brace 7 to befastened upon the ground at whatever elevation and distance is mostconvenient from the base of uprights 2, The pivotal connection of tie 4to uprights 2 enables the uprights to be adjusted slightly to make themplumb; and the bottom of eachbrace 7 can be moved correspondingly.Additional sections 2 may be added vertically to the uprights asrepresented in the top of Fig. l, the sections being held together by asingle pin as represented and the sections thus added being held uprightwhen the wall has risen to a sufficient height by wire ties 9 which maypass through the wall which is being constructed and be tied to asupport onthe other side of the wall. When the apparatus is used forbuilding a concrete wall these ties maybe fast to the uprights on eachside of the wall. When used for building a brick wall, in which the wallis not between the uprights as in the case of concrete, the ties maypass between bricks of the wall and be fast to the floor within thebuilding as indicated in Fi 2. A convenient fastening is illustrate inFig. 3 where a windlass bolt 10 is represented in the upright, piercedby a hole ll, the wire being passed through the hole, leaving a littleslack between the bolt and the fastening in the building,`or theupright. rllhe bolt 1s rotated by means of a wrench, a crank or othersuitable means, winding the wire about the bolt, and drawing the uprighttoward the building as much as necessary. When plumb, the nut on thebolt may be screwed tight, thus holding it. This isa substitute formethods heretofore used in which it is customary to omit a brick in thewall, occasionally, to insert a stick of timber, and also to inserttimbers through windows of the structure. By this improved method thewall is built in complete form without omission of bricks; and thewindows are unobstructed and in condition for finishing by workmen whilethe staging still remains in place. When the staging is taken down thetie wires 9 may be cut close to the wall, the portion lof the wire inthe wall being left there or being withdrawn at pleasure.

Flanking may be laid on the cross ties l laid outside. When extendedthey may be held by an additional row of uprlghts, one of which isindicated in dotted lines in Fig. 5, The tying of the upright 2 to thesill 1 by a pin as shown in Fig. 5 generally renders this third rowunnecessary.

One feature of the invention relates to improved planking in which thelanks are butted end to end over each le ger beam. As hithertoconstructed this wouldl be unsafe; but by the present invention one ormore hooks 51 is formed on the under side of each board or plank,projectin beyond the end of the lank. These ma e of flat sheet metal anhave their ends ent downward to engage the farther side of the ledgerbeam. A recess or notch 52 is formed in the end of the next adjacentplank, to

register with each hook. Each plank may then be put in place or removedindependently of its neighbors at each end, and yetit safely overlapsits supporting ledger beam at each end and is preventedby the depend inghook 5l vfrom falling olf and constitutes a longitudinal bond in theframe. As the end of the plank actually rests upon the ledger beam theweight is transmitted downward primarily without reliance upon theextension. The notches 52 are so narrow that they do not interfere withthe general continuity of surface of the planking. By this means thenovel feature of a smooth top walk or runway is provided on whichmaterials may be brought and dumped into the mold hereinafter to bedescribed.

Fig. 5 represents the apparatus as it may be used in laying concrete,the wall being formed between the uprights. In this figure the use ofthe old style of planking 1s represented, not embodying the feature ofthe invention last described. Side boards 2O are laid and the concreteis deposited between them. Until supported by concrete they may beretained in place by turn-buckle spreaders 21. When the wall is finishedthe uprights 2 are lifted from the sills 1, the boards tumble down, andthe sills may be pulled from under the wall. While in place, the sillselfectually tie together the bottoms of opposite uprights, preventingspreading. The upper parts of the uprights may be tied by wires passedfrom one upright through the concrete and between the boards to theupright on the other side, and they may be fastened like wires 9 orotherwise. In cases -where this apparatus is used for forming a cellarwall or other wall against an embankment, the braces 7 are placed onlyon the lower side of the wall, the uprights on the opposite side beinclose against the bank or even being embe ded therein. The concrete wallwill then be built very close to the bank. When finished, the ap aratuson the bank side is taken down by ifting the uprights 2 verticallyupward and then by passing a hook down through the `vacant space thusformed, to holes 22 1n the outsides of the boards, thus lifting them.The sills may be drawn out horizontally on the lower side. Each sill isnotched as at 41 and the upright 2 has a prong projecting into andfilling each notch. The exterior dimensions of the sill, in crosssection, are elsewhere uniform throughout its length, and therefore thehardening of the concrete does not preventthe withdrawal of the sillendwise. If preferred, the sill may be tapered a little from the side onwhich it is to be withdrawn. This is seen in Fig. 5 where the sillappears to taper very slightly from its remote end toward its near end.

rlhe apparatus can be used repeatedly, thus savlng over the methodsheretofore used in which the woodwork is splintered or destroyed intaking it down. Very little excavation is needed on the bank side of thewall, thus saving cost in that respect also. The boards 20 mayl beprovided with any desired faces, plain or matrix, to give surface formto the concrete. When in use each upright is t-ied to its sill byengagement in the notch in the sill, about which it can swing a little,from which it can be removed by lifting, but in which it can moveneither outward nor inward while in lace; and it may be held down bypins 6, if desired. Diagonal or horizontal ties and braces 35 may beemployed between the uprights, if needed, and these also may be fastenedwith bolts, passing through the slots 3.

Another feature of the invention relates to the manner of supportin theface forms for the work, in contact with which the wall which is beingconstructed is built. These are illustrated as used in connection withthe concrete construction and embody a gang system and means for easyadjustment thereof to different elevations and to different angles fromthe vertical. At each upright is provided a section of timber 60 whichstands vertical or nearly so and which is supported from the upright bymeans of bolts 61 and straps 62 and which constitutes a secondaryupright and in turn supports a facing 63 for the work. This facing mayconsist of boards nailed upon the timbers 60 and extending from oneupright to its near.- est adjacent upright on the same side of the work;and the total width of the boards 63 in a vertical direction may be thetotal amount which it is desirable to construct at one setting ofconcrete. This face form is adjustable to different elevations byraising the straps 62 upon the uprights to the desired place where theyare held by pins or any other suitable or desired manner. The face formis adjustable to different angles from the vertical by means of itssupporting bolts 61. These have a portion 64 which is acasoa screwthreaded through the strap 62 and another portion 65 which is screwthreaded into a horizontal ivot 66 set in the timber 60, the two threa sbeing in opposite directions. Upon twisting the bolt 61 by means of awrench or otherwise, it is propelled through the strap 62 in onedirection and at the same time moves the pivot titi and timber in theopposite direction. ln operation the straps 62 are raised so that the'lower part- ,of face form 63 is at the desired elevation and the lowerbolt 61 sets it laterally at the position ofthe desired face of themold. Then the upper bolt 61 is adjusted until the face form (33 standsplumb or at such angular variation from a plumb position as is required, in case the wall is being built with an inclined face. Thisadjustment is possible because the connection between bolt 61 and timber60 is pivotal, the bolt being screw threaded transversely through 'thecylindrical pivot G6. To raise the apparatus past one of the jointsbetween an upright and its neXt higher sectional upright, either bolt 61may be withdrawn by unscrewing it, the portion 65 being smaller indiameter than portion 64 so that it will pass through the screw hole ofL64. Tige straps 62 are preferably made in shapeto lap around both sidesof the upright as shown clearly in the plan view, (Fig. 8) so that theyvslide up and down readily thereon with no danger of falling off and sothat they may exert either a push or a pull upon the timber 60. By thisarrangement all the boards which are to form the face of the mold for asection ofl considerable vertical depth are fastened together in a gangand are adjusted in this gang arrangement, one adjustment serving forthe whole gang. Vvhen ready for the next higher setting the entire gangis raised and set at once. If desired, two or more gangs may be workedabove each other on the same uprights, the lower one being re tained inplace as long as necessary Yfor hardening of the concrete, while one ormore gangs are set above it. The repeated use of boards in this manneris a measure of great economy as compared with the now prevalent methodof nailing the mold in place with the accompanying waste of lumber'which it involves.

Another feature of the invention relates to the formation of theinterior face of theY mold in cases where the wall is to have aY hollowspace. To form such a hollow Iprovide a core composed of three piecesmarked respectively 7G, in the middle, and 71 and 72; at each side ofit. In a wall eighteen inches"V ing a rectangular exterior.V When theconcrete is set sufficientlypthe central one may be drawn upward easilyafterY which those on each side can easily be removed. In such a wall itis desirable to tie the two sections of the wall together periodically.This may be accomplished by setting bricks across, bridging the hollow,after the core has been withdrawn, and then continuing the uphuilding.In such cases the lower edges of the planks should be notched to receivethe thickness of the bricks, as seen in Fig. 1 at the lower corn-er ofthe plank under the reference numeral 72, where the brick is seenoccupying a notch in the corner of the plank. When the core planks arenot supported on tie-bricks or the equivalentI thereof they aresustained from the ledger board 4, by cords passing through eye-bolts73, the cords being omitted in .the drawing for the sake of clearness. Y

It will be understood that the combination bonding platform composed ofboards 50 and their hooks 51 may be placed anywhere on the ledger boards4,'although illustrated onlyl on one outer side thereof, and inparticular it may be placed between the two uprights, or Ya single lineof boards may be placed there affording convenient facilities fordumping concrete material into the mold.

When the gan@ arrangement of boards to form the outer fhce of the moldis used, it is Vdesirable ,that the boards be put together with matchedjoints as shown in Figs. 1 and 4 and it is of particular advantage tobevel the outside of each board at the top down-` ward from its jointwith the board above it as at 67. There is a tendency for water to entercracks between boards such as this, causing swelling and causing othertroubles. The enlarged opening thus formed at the outer edge of thiscrack prevents trouble from this source, the water running off insteadof running in.
